Improvement in sugar-cutting machines

IMPROVEMENT IN SUGAR-CUTTING MACHINES.

Specification forming part of Letters Patent No. 33,5 5 H, dated August20, 1861.

' reference being had to the annexed drawings,

making apart of this specification, in which- Figure l represents a planView, and Fig. 2 a vert1calsection,of a sugar-cutter having myimprovement applied thereto, like letters indicating the same parts whenin both figures.

My invention has for its object the division of loaf-sugar into smalluniform blocks for family use; and it consists in a peculiar con--struction and arrangement of four sawingcylinders to operate together inconnection with a feed-trough, as hereinafter described, so ithat theusual disks of sugar, in passing between the said cylinders, shall begrooved in each side in such a manner that they will become perfectlydivided, or broken apart into small uniformblocks, on falling into thereceiving-box below, whereby the great deterio ration and wasteheretofore produced by sugarcutters is entirely avoided.

In the drawings, A A and B B represent the upper and lower cylinders,respectively; 0, the feed-trough, and D the receiving-box.

The upper cylinders, A A, are each provided with a series of circularsaws, cc, secured adj ustably at any regular distances apart across thecylinder, so that when the said cylinders are secured at a shortdistance apart, parallel to each other, upon the supporting-arches ff ofthe receiving-box D, their respective saws e 6 will be directly oppositeto each other or in the same planes, substantially as seen in Fig. 1.

The lower cylinders, B B, are each provided with a series oflongitudinally-arranged saws, g g, secured around their peripheries, soas to project radially therefrom at any regular distances apart, as seenin the drawings. These cylinders B B are made so as to have an inch(more or less) play longitudinally on their respective shafts; and thepulleys h h, by which they are driven, are provided with projections orcams on each side, so that when the cylinders are rotated the said camsalternately come in contact with projections k k on the receiving box orframe and the arms ll projecting therefrom, and thus are caused tooscillate longitudinally and in opposite directions, giving the requiredoperative motions to the saws? The pulleys h h of the said cylinders B Bare of like diameters and are connected by a cord, m, or otherwise, soas to rotate the cylinders in opposite directions, and at the same timekeep them in such relation to each other that their respective saws g gshall successively come directly opposite to each other, as seen in Fig.2.

The feedtrou'gh O has a series of vertical slots in each side, throughwhich the circular saws e 6, respectively, project into the trough abouta quarter inch, more or less, substantially as seen in the drawings.

The upper cylinders, A A, are driven by the pulleys a n, which areconnected by means of a cord, 0, or otherwise, so as to rotate in thesame direction; and one of the said pulleys is also connected to oneofthe lower cylinders by means of the pulley h thereon, the drivingpowerbeing applied to .the other lower cylinder B, by means of a band-wheel,p, or otherwise. The distance between the cylinders A A corresponds withthat between the cylinders B B.

In the operation of this machine the eyliuders rotating in thedirect-ions indicated by the arrows, and the usual disks of loaf-sugarbeing placed edgewise in the feed-trougl1 c, the saws e e on thecylinders A A cut narnow vertical grooves in each side of the disks,directly opposite to each other, and the said disks, descending, arecaught between the cylinders B B by the saws g g, which latter, beingreciprocated rapidly in opposite directions by the oscillating motionsof the cylinders, out like narrow horizontal grooves in the said disks,which latter, thus grooved, and also accelerated in their motiondownward by the rotary motions of the cylinders B B, break into uniformblocks as they fall into the receiving-box D, and thus the dcteriorationand waste, consequent upon the production of the innumerable smallirregular pieces by the cutters heretofore used, are avoided.

Having thus fully described my improved together, in combination withthe feed-tr0ugh machine and pointed out its utility, What I G,substantially in the manner described and claim as new therein of myinvention, and defor the purpose specified. sire to secure by LettersPatent, is CHARLES TEOKELNBURG.

Providing the cylinders A A and B B with Witnesses: the saws e c and gg, respcctive1'y,as described, BENJ. MORIsQN, the said cylinders beingarranged to operate B. F. SHATTUOK.
